A further advantage of this construction, 1s, that we are enabled to place intermediate these recesses cooling fiues forgradually cooling the metal as it passes over the projecting portions H to the grease pot. Attention is also called to our particular construction, which is the casting of the walls and bottom of grease and metal pot integral, that is of a single casting, and then forming the grease pot by placing therein a transverse vertical partition separated at its lower end from the bottom of said casting sufficiently to allow the passage of the plates from the metal pot into the grease pot, as clearly shown in Fig. 1.

i It will be noticed that the left hand end wall of the pot extends above the opposite end thereof, and that the outer or adjacent side wall of the pan-like partition extends a corresponding distance above the opposite wall thereof which forms a grease pot above the plane of the metal pot to afford a receptacle for the grease above the metal line of the metal pot. As will also be seen, we provide the metal pot with feeding rolls for catching and carrying them forward through the metal to the grease pot, in contradistinction to the usual method of pushing them through by means of tongs, thus only requiring the placing of the plates by the operator in the flux box. In this manner one person can feed a double machine thus increasing the output, and doing away with the expense of one man, as two would be necessary if the feed rolls were not provided. lVe also make the feed rolls removable, as before described, the particular object of which is to permit any one or more of the operating parts to be removed from the pot without interfering with any of the other parts, and without removing the metal for that purpose. \Ve are thus allowed ready and convenient access to all the parts for the purpose of inspection or repair, as will be readily understood.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. A combined metal and grease pot having the walls and bottom thereof cast integral and the side walls unbroken, a detachable pan-like vertical transverse partition placed wholly within the side walls of the pot and extending to near the bottom thereof to make two distinct receptacles, and heating means for maintaining the metals in the two receptacles at diiferent temperatures.

2. A combined metal and grease pot having the walls and bottom thereof cast integral, one end of the pot extended above the other, and a vertical transverse partition composed of side and end walls, the outer side wall being extended to correspond with the extended end of the pot to form a grease pot 7 above the metal pot.

3. A metal pot for the purpose described, having transverse recesses forming projecting portions between them, and cooling flues beneath the said projecting portions, substantially as described.

4. The combination with a metal pot having transverse recesses in its bottom, of a series of rolls, and separate and removable boxes for said rolls placed in said recesses.

5. The combination with a metal pot having transverse recesses in its bottom, of a se ries of rolls, series of separate boxes for said rolls seated in the recesses, and separate removable holding means for each box extending above the metal line.

6. The combination with a metal pot, of a series of pairs of rolls, upper and lower boxes for the rolls of each pair, parallel vertical rods for holding the lower box of each pair, and a'central rod for holding the upper box of each pair of rolls. 7

7. The combination with a metal pot, of a series of pairs of rolls, separate upper and lower boxes for the rolls of each pair, and separate removable holding means for the upper and lower boxes which means extend above the metal line.

8. The combination with a metal pot having transverse recesses in its bottom of a series of pairs of rolls, lower boxes for the lower rolls seated in said recesses, separate upper boxes seated on the lower boxes, and a removable holding means for said boxes.

9. The combination with a metal pot of a series of pairs of rolls, lower boxes for the lower rolls of each pair, parallel vertical rods engaging and holding the lower boxes, and separate upper boxes for the upper rolls supported between the said parallel rods.

In testimony whereof we affix our signatures in presence of two witnesses.
